The time before mitosis when the DNA and chromosomes replicate is called what?

Explanation:
Interphase is the time when the cell gets ready to divide by copying its DNA. During this phase, the cell grows and duplicates its genetic material in the S phase, so each chromosome has an identical copy (sister chromatids) to separate later during mitosis. This replication ensures that, when the cell divides, each new cell receives the same genetic information. After interphase, mitosis and cytokinesis happen, with stages where chromosomes condense, line up, separate, and the cytoplasm divides to form two cells.
